Just to be clear, are you saying that he should generate via an LLM, or hand-write, a python script, then run analysis on the data?

Today I'd have the LLM write the script. Why not?

Um sure, point being llm writes said script

You assume, but I’ve known normies to just ask copilot to hallucinate figures instead of writing scripts.

That is what should be expected. your harness should translate write me the figured, to create a script to analise this and produce real results, and then verify them again agains source data before presenting. Not sure why you're asking normies to write python scripts.

Yes, the LLM will have to write a script to process them, just wonder how it differs from other LLMs to categorize and create useful insights. I tried this with Opus and Actual, and Opus didn't label a lot of transactions where the payee's name includes gasstation, food and other obvious purchases.
